    Replacement backup battery for Teac CR H100 HiFi

    Hi I have an old Teac CR-H100 hifi that has a leaking and worn out backup battery. I was looking for a suitable replacement component. Would something like this be ok:

    https://www.ebay.co.uk/itm/362488422916

    Seems to be the right size. It it NiMh but the original is NiCad but I can't seem to find any NiCad type replacements.

      The NiMh Varta V40H looks fine, just make sure the size will work. The PCB has extra holes for one size wider.
      It might be a 1/3AA size 17mm x 14mm dia. but those are all big 110mAh and yours is 35mAh.

      TEAC charging circuit is 1k ohm to 4.3V standby power, so ~0.7mA constant charge.

              APC BR1000G battery backup has a weird issue sometimes a bad battery icon and making a weird sound for about 30 seconds
              by sam_sam_sam
              This started a few days ago and does this about every 8 hours

              After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup

              The battery backup is about 3 or 4 years old

              Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start

              Macbook Air M2 A2681 Kernel panics after screen replacement
              by reformatt
              Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

              It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

              Clevo PD50PNN won't boot after BIOS Backup
              by Chris_stand
              Hello,

              i hope to find help her in the forum. It is a littlebit tricky. I searched many Days about disabling IntelME that was may major task. So i have a Clevo PD50PNN motherboard.

              At first i tried to Backup the BIOS with tools direcly from Windows(normaly i am a Linux user). But no full success because not every part of the bios was readable. So i bought a modified CH341a for a Backup.

              Backup worked but since the backup the Laptop is not booting anymore. I flashed the newest Version oft the BIOS with success, verfiy everything ok.
              But the...

              Unknown transformer : how to find a good replacement part ?
              by the_rem
              Hello guys,

              I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

              I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

              BIOS Backup / extract 16MB .bin - Lenovo ThinkBook 13s G3 ACN - 20YA0005GE
              by DiddiAb
              Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.

              I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost...
